Photosynthesis

What is the equation for photosynthesis

sun + CO2 + H2O →C6H12O6 + 6O2+ H2O

photon

particle of light

How are wavelength and frequency related

they are inversely related

increased wavelength=decreased frequency

decreased wavelength=increased frequency

what occurs in the process of photosynthesis

capture of light energy and makes usable chemical energy

where does the light reaction of photosynthesis occur

thylakoid membrane of chloroplast

what are the reactants and products of the light reaction

sun + H2O → ATP and NADPH

what is the electron source for the light reactions

water

what happens when water splits

another electron replaces the electron that the chlorophyll lost

O₂ is a byproduct of water splitting

what happens with the chlorophyll during light reaction of photosynthesis

chlorophyll is struck by a photon and loses an electron

what is chlorophyll

a reactive pigment and where the light reaction occurs

what does the photon do

the photon causes the electron to get excited and gets transferred to an electron carrier

what series occurs during the light reaction

redox reactions

what is the final electron acceptor of light reaction

NADPH

electron shuttler

can be oxidized or reduced

where does the light independent reaction occur

in the stroma of the chloroplast

what are the reactants and products of light independent reaction

CO2 + ATP + NADPH →C6H12O6

what is nadph doing in light independent reaction

carrying and transporting electrons

how is solar energy captured in light dependent reactions

captured in the bonds of ATP and NADPH

energy converted into bonds of sugar

what is the connection between light and light independent reactions

light reaction captures light energy as electron energy then light independent takes the electron energy and places it in the bonds of sugar (Glucose)

what is chlorophyll a

most important light absorbing pigment in plants

absorbs blue and red light, reflects green

what is flourescence

“energy transfers” as photons

what does an increased surface area mean

more photons captured and more photosystems

what is the first step of the C3 cycle

6CO2 combines with 6RuBP (5c molecule)

catalyzed by rubisco

what is the second step of the C3 cycle

6 6 carbon molecule splits into 12 (3C) molecules of PGA

what is the third step of the C3 cycle

using ATP and NADPH from light dependent reactions, 12 PGA is converted into 12 (3C) molecules of G3P

what is the fourth step of the C3 cycle

some G3P molecules go make glucose while others are recycled to regenerate RuBP acceptor

2 for G3P

10 to be recycled into 6 (5C) molecules of RuBP

what can the new RuBP molecules do

restart the cycle

What is the input of the C3 cycle

6 CO2, 18 phosphates from ATP, 12 electrons from NADPH, 6RuBP

what is the output of the c3 cycle

2 G3P, 6 RuBP

where does the C3 cycle occur

stroma
